BAIL JOINT.

i Application led August a0, 1925. serial No. 51,430.

T0 all 107mmc't may concern.'

Be it knon'n that I, JOSEF Kovnmjli, a citizen ot the VUnited States, residing at Corvallis, in the county ot Benton and State oi' Oregon, have invented certain new and useful Improven'ients in Rail Joints, o'l.I which the following is a specilication.

This invention relates to new and useful iu'iprovements in rail joints.

The primary object ot the invention is to provide an improved torni ot joint for rail ends by means of which the usual .fish plate connectors may be dispensed with.

Other objects and advantages ofthe invention will be apparent during the course o if the following description.

In the accompanying drawing forming a part of this specification and in which like numerals are employed to designate like parts throughout the same.

Figure 1 is a side elevational view of a pair of rail ends which are joined by the improved means embodying this invention,

Figure 2 is a top plan view of the strucn ture shown in Fig. 1,

Figure 3 is asimilar view to Fig. 1, partly shown in section, of' an improved form of lail joint embodying this invention,

Figure 4c is a longitudinal sectional view of one of the rail ends, taken upon lines IV-IV of Fig. 3, and

Fig. 5 is a vertical sectional view of the second rail end shown in Fig. 3 and taken upon lines V-V of this latter figure.

In the drawing, wherein for the purpose o1 illustration is shown a preferred embodiment of this invention, the numerals 5 and 6 designate the joined rail ends which include tread portions 7 and 8 respectively.

In Figs. 1 and 2 the adjacent end portions of the treads 7 and 8 are illustrated havv ing formed therein grooves 9 and 10 which extend longitudinally of the rail. ends and are of dove-tail-shape in cross-section and open thru the top faces of the treads 7 and 8. Positioned within these grooves 9 and 1() and conforming in cross-sectional shape therewith is a key 11 which is intended to prevent relative lateral movement of either of the rail ends 5 or 6 in respect to the remaining end. y

In Figs. 3 to 5 inclusive the rail ends 5 and 6 are illustrated as having formed therein the longitudinally extending pockets 12 i and 13 which are formed primarily in the web portion or the rail. ends and communicate with 'the grooves 9 and 10. These pockets 12 and 13 have pivotally mounted tl'ierein the dogs 14 and 15 which have their free ends Apressed upwardly by the leaf springs 16 and 17. The under tace of the key 11 is formed with notches 18 and 19, adjacent the end portions of the key, for receiving the upper ends of the dogs 15 and 16.

To permit these railends to be disconnected, transverse openings 2O and 21 are formed therein and through which the pin 22 maybe inserted for permitting it .to luear against the upper edge of' a dog for forcing the latter downwardly against its spring to remove the end of' the dog from the key notch in which it is intended to be seated. Figs. 3 and Ltshow the transverse openings 20 and 21 as being Jformed with 'beveled end :faces 23 which function to guide the pin 22 into a proper position for engaging a dog.

It is to be understood that the forms of this invention herewithY shown and described are to be taken as preferred examples ot the same, and that various changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit ot the invention or the scope of the subjoined claims.

I-Iaving thus described the invention, I claim i 1. In a rail joint, a pair. of rail ends having longitudinally extending grooves formed in their tread portions with each groove of dove-tail-shape in cross-section a d opening through the end tace ot the rail end, a.

ltey ot' dove-tailshape in cross-section received in the grooves formedl in said rail ends, said key having notches formed in its lower face, and upwardly spring pressed dogs carried by said rail ends and adapted to have their ends received in the notches formed in, said key for preventing relative longitudinal movement between the rail ends andthe key.

2. In a rail joint, a pair of rail ends having longitudinally extending grooves formed in their tread portionswith each groove of dove-tail-shape .in cross-section and opening .through the end face o1' the rail end, n key of dove-tail-shape in moss-section received in the grooves formed in said rail ends, said key having notches :formed in its lower face, said mi] ends having pockets formed n their Web portions which con'nnuncate with the grooves, a pvoted dog n each pocket adopted to have its free end enter a notch ln said key, :md :1 spring in each pocket below its respective dog for holding the latter in its notch entel- 10 ing position.

In testimony whereof I affix my signature.
